New oceanographic models for ocean analysis and forecasting

11.03.2008
Pierre Bahurel and his team from Mercator Ocean in France have, together with ESEOO in Spain, developed new oceanographic models that will help us to understand the evolution of the climate over the last decades and to provide an ocean analysis and forecasting service on a daily basis.

Ocean is an integral part of our environment, upon which many depend for survival, and it is a basic element of the Earth’s climate. It is also an important site of transit for both goods and people. Therefore, understanding both the state of the ocean and the ways in which it might change is crucial.

Pierre Bahurel and his team from Mercator Ocean in France have, together with ESEOO in Spain, developed a global eddy-permitting model which allows a realistic representation of the main ocean currents.

They have also been able to study for the first time the coupling between sea ice and a global eddy-permitting ocean. Understanding this coupling is essential to efforts to realistically simulate circulation in the high latitude ocean, which has consequences for large-scale ocean circulation and deep water formation.

Achievements have also been made at a more regional level, especially in the North Atlantic area. The research group has managed to represent correctly the Gulf Stream pathway and in particular the separation of the current from the coast at Cap Haterras to become a zonal jet in the Atlantic.

A supercomputing infrastructure is essential for oceanographic modelling in order to generate ever more realistic simulations of the ocean’s behavior. Computation capacities provided by DEISA (Distributed European Infrastructure for Supercomputing Appications) have enabled research group to carry out interannual simulations, which are crucial for testing the validity of the models, for setting up systems of operational oceanic forecasting, and for deepening the understanding of the ocean more generally.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Shape matters when light meets atom

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
